HTLP metamorphism and fluid-fluxed melting during multi-stage anatexis of continental crust (N Sardinia, Italy) [PDF]
Journal of Metamorphic Geology, Volume 41, Issue 1, Page 25-57, January 2023., 2022 The Variscan high-grade metamorphic basement of northern Sardinia and southern Corsica record lower Carboniferous anatexis related to post-collisional decompression of the orogen. Migmatites exposed in the Punta Bianca locality (Italy) consist of quartz +

Journal of Metamorphic Geology, Volume 41, Issue 7, Page 967-995, September 2023., 2023 Abstract Two eclogite samples from the Haut‐Allier record a prograde evolution from ~20 kbar, 650°C to 750°C, 22–23 kbar followed by heating up to 850–875°C and partial melting. Incipient decompression in high‐pressure granulite facies conditions (19.5 kbar, 875°C) was followed by exhumation to high‐temperature amphibolite facies conditions (<9 kbar ...

Geochemistry, Geophysics, Geosystems, Volume 24, Issue 3, March 2023., 2023 Abstract The Barrovian metamorphism of the Lepontine dome is manifested by isograds that cross‐cut tectonic nappe contacts, which is commonly interpreted as metamorphism that occurred after nappe emplacement. However, the pervasive mineral and stretching lineation in amphibolite facies, associated with top‐to‐foreland shearing, suggests that peak ...

Tectonics, Volume 39, Issue 12, December 2020., 2020 Abstract The Coompana Province, located between the three cratonic blocks of Australia, is significant for understanding the Proterozoic assembly of the continent. However, the basement rocks are completely covered and poorly understood, and as a result reconstructions are poorly constrained.

Three-dimensional field perspective on deformation, flow, and growth of the lower continental crust (Dharwar craton, India [PDF]
, 2008 The study of fabric development and juvenile batholith emplacement across the tilted crustal section of the Eastern Dharwar craton shows that horizontal, constrictional deformation affected large volumes of the midcrust and lower crust at the time of ...

Primary crustal melt compositions: Insights into the controls, mechanisms and timing of generation from kinetics experiments and melt inclusions [PDF]
, 2017 We explore the controls, mechanisms and timing of generation of primary melts and their compositions, and show that the novel studies of melt inclusions in migmatites can provide important insights into the processes of crustal anatexis of a particular ...
